简单的onload在JSFIddle中不起作用 [英] Simple onload doesn't work in JSFIddle
问题描述
当加载
因此，当
载入事件触发时，您将绑定另一个 load 事件处理程序。 您的新的 load 因为 load 事件已经被触发，因此被调用。
将菜单选项更改为无包装方法之一。
第二个问题：
load 事件触发窗口对象，而不是 body 元素。 / p>
您需要将该属性分配到正确的位置。
onload = function（）{
alert（LOADED！）;
}

Simple document.body.onload event should trigger a javascript alert, but doesn't work but it works fine in my text editor -> browser. I switched the libraries around to jQuery to None (pure JS), still nothing, can someone explain to me what's going on and why it doesn't work in fiddle but works fine in my text editor?
This works:
<body>
Why
<script>
document.body.onload = function(){
alert("LOADED!");
}
</script>
</body>
Your first problem:
You have configured JSFiddle to run your JS when the load event fires.
Consequently, when the load event fires, you bind another load event handler.
Your new load event handler is never called because the load event has already fired.
Change the menu option to one of the "No Wrap" approaches.
Your second problem:
The load event fires on the window object, not the body element.
You need to assign the property to the right place.
onload = function(){
alert("LOADED!");
}
